Due some issues with EICAS screen, I decided to uninstall and reinstall the
Sim-Avionics 1.7 software on the Avionics computer.

The result: EICAS issue persists and on top of that ,all annunciator lights don't work? including the Flaps transition lights. The only lights working properly are the Gear position and Flaps TRANSIT and EXT. lights .

EICAS:
As per Steve's advice I checked the Main Panel DU and Lower DU selectors position in the SYS Board.the Position matches.
Also The AC /DC power has been checked.
Remarks: by draging the server page over the black EICAS Screen, the two
STBY instruments come up, and disappear again when draging the server page away.

Recall autopilot values and flps values has been done!

ANNUNCIATORS:
The SYS Board test mode all annunciators light up.

During an approach when lowering the Gear and arming the speedbrake
The fuel annuniator on the six pack lights up.

You need to explain a little more what the EICAS problem is. If it's a black screen give this a try.
Go to your Sim-Avionics root folder and open monitor setup. Make sure all your screens are switched on (all screens attached to your avionics PC that SimA runs on) and then go through the monitor setup process and correctly assign the monitors, then restart SimA.

With regards annunciator lights you need assign them to the correct functions in the sysboard controller, the reason your seeing the fuel light come on when the gears down is because that's the light currently assigned to 'gear down'. You need to assign it to the 3 green lights over the gear handle.

If you're unsure how to assign lights let me know and I can take you through it.

Your initial problem with the EICAS going blank sounds more like an OpenGL display problem across the GFX cards.

What GFX card are you using ?
How is it connected ? - Direct VGA/DVI or via an HDMI or Display port converter ?

The first things I would try are :
1) Ensure you have installed the latests GFX drivers.
2) Try running the EICAS in non-fullscreen mode... ie with a border.
Click on the EICAS and press B to display the border.

If this doesn't work - send me an email and we'll try and work something out.

Your second question with the annunciators just sounds like an assignment problem.
Did you backup your previous ASSIGNMENTS.INI from the \SysBoard Interface folder ?
If you did - simply copy the backup INI into the new SysBoard Interface folder.
If you didn't.
Press Clear all Inputs (from the Input Assignments tab)
Press Clear all Outputs (from the Output Assignments tab)
Import : \Imports\737_JETMAX_MIP_IMPORT
SAVE

If this doesn't reset your annunciator assignments then I think your annunciator 'connectors' are connected to your SYSboard in a slightly different order to standard.
The quickest solutions is to reassign the problem annunciators on the Output assignment tab.
Use the checkbox on the right hand side of each function to verify if the correct output is assigned.
If the annunciator does not come on, 'Clear' the assignment and then press Reassign.
Follow the simple instructions, find the correct LED using the Y/N keys, press Use LED.
Remember to press SAVE every so often.!_________________Mark Hastings
